Dear Chris,
After I added parameter vmalloc=256M to my grub2.conf problem resolved.
I don't know need will add it parameter to default grub2.conf or not, but when I
used my XFS partition with default vmalloc I did't see problem. It's just
interested
for me and therefore I asked Community.

I suggest also asking about this directly on the XFS list. XFS is going to be the
default fs for Fedora 21 Server, and will include i686 arch as far as I know. So we should
try to squash any related i686 bugs or non-graceful failures as possible.
